Ventilation: Your Defense Against Covid 

“The CDC has finally said what scientists have been screaming for months: The coronavirus is overwhelmingly spread through the air, not via surfaces”

Last week, the CDC acknowledged that cleaning surfaces to prevent transmission of the coronavirus is pure hygiene theater. You can put away the bleach, cancel your recurring Amazon subscription for disinfectant wipes, and stop punishing every square inch of classroom floor, restaurant table, and train seat with high-tech antimicrobial blasts. COVID-19 is airborne: It spreads through tiny aerosolized droplets that linger in the air in unventilated spaces. Touching stuff just doesn’t carry much risk.
